Packaging plays critical roles to protect the product from the environmental hazards and vice versa. Many researches have been carried out to develop a new type of packaging, and the smart packaging is growing fast in global packaging market. In smart packaging system, the sensor collects the information on change in package condition and environment. The system includes the indicators for gas, temperature, tilt, and impact etc.In this study, The porous polymer beads as chemosensors to detect CO2 were prepared from the acrylamide containing pH indicating function by using the precipitation polymerization. The chemosensible polymer bead would change a color when it chemically react with CO2 occurred from foodstuffs. The color changes were determined with various concentration ratio of carbon dioxide. It was measured by using the SEM and colorimeter. |
